Whilst there is a thing called TFP (time/trade for prints/photos) THIS ISN'T IT. TFP usually involves a model starting out, who wants to build up a portfolio or photos for social media but can't afford a photographer (often has some modelling experience and can take direction) A photographer starting out, who wants to build up a portfolio or photos for social media but van't afford models (has some photography experience but not necessarily in portraits/fashion) Optionally others such as hair/nails/makeup/clothing who want to have photos for marketing/social media but can't afford a model and photographer The agreement says who will do what and how many finished photos each party will get. This is just someone who wants a pamper session for free. There's nothing in it for others - if they want to practice I'm sure that they have friends, family or neighbours who actually mean something to them they could treat to a pamer session rather than giving it free to a random stranger.
